According to Craig Harris of IGN on a recent Nintendo Voice Chat Podcast, Nintendo may be getting rid of having friend codes for each individual game on your system.
“I’ve heard rumors that friend codes are going away. It’s going to be a universal system code but its still going to be a code…There’s no online account, it’s just your system has the number.”
While its not the integration with Club Nintendo that we would like to see, its at least a step in the right direction.
